To dllwho'm may concern:

Be it known that I, ALBERT D. WISWALL, a c tizen of the United States, residing at Utica, in the county of Oneida and State of. New York, have invented a new and useful Improvement in a Contact-Oiler, of whicli the following-is a specification. This invention relates to a device for oiling thecontactplates of controllers, the object of the invention being toreduce Wear upon the contact plates and the contacting fingers Which they engage, thereby prolong- I ing the life of the controller. 1

' The ii'ivention consists of the novel features of construction, hereinafter fully described, and pointed out in the claims, in

I I f v Figure 1 1s a partialsection taken vertically through a controller casing showing my invention appliedv thereto and in elevation. Fig. is a section on the line .2-2 of Fig. 1. Fig. 3 isan elevation of'my oiler partly broken away. and shown in section.

In these drawings A represents the casing, whiclrincloses the contact plates and fingers and within which my device is also arranged.

A represents thehandleby" -n1eans of ivhich the controller shaft A is rotated.

-This shaft carries the usual contact plates B, which engage fingers C. These parts are all of the usual construction and are .in use at the present time.

My invention comprises two brackets D which are secured Within the casing A adjacent the upper and lower'ends of the said casing and which are carefully insulated from the casing as shown at D in Fig. 2. In these insulated brackets D are journaled loosely end portions'of a rod E and between the said brackets the rod is covered with-felt or any other suitable oil absorbing and retaining material, as shown at E. This ina- '13. By oiling these contact plates and. strips,

the friction between them is reduced and wear of the plates, considerably obviated.

Having thus fully describedany invention, What I clann as new and desire to secure b Letters'Patent, is

'1: The combination with a controller shaft, contact plates thereon of a rotatable rod, said rod being lncased 1n a lubricant absorbing material, said-material being inengagement with the contact plates.

1 "2 The combination with a controller haying a rotatable shaft, cbntact plates thereon,

andfingers engaged by the said plates, of a rotatable roll of lubricant saturated material 1n engagen'ient Wllll the contact plates,

and means for insulating said roll from the controller casing.

S; The combination with a controller comprising a casing, shaft, contact plates and fingers, of brackets" carried by and insulated from the casin a rod journaled in said brackets said rod being parallel to the controllershaft, and a covering of absorbentinaterlalsaturated Wlth a suitable lubricantcarried by the said rod and in engagement with the contact plates, as and for the purpose set forth.
